Browser Support

The outlineStyle property is supported in all major browsers.

Note: The outlineStyle property is not supported in IE7 and earlier. IE8 requires a !DOCTYPE. IE9 supports it.

Tips and Notes

An outline is a line around an element. It is displayed around the margin of the element. However, it is different from the border property.

The outline is not a part of the element's dimensions, therefore the element's width and height properties do not contain the width of the outline.

Example

Change the style of the outline:

<html>
<head>
<style type="text/css">
#ex1
{
border:1px solid red;
outline:green dotted thick;
}
</style>
<script>
function displayResult()
{
document.getElementById("ex1").style.outlineStyle="solid";
}
</script>
</head>
<body>

<div id="ex1">This is some text.</div>
<br>
<button type="button" onclick="displayResult()">Change outline style</button>

</body>
</html>
